Hybrid membranes consisting of polyvinylidene fluoride (PVDF) and electrochemically-fabricated graphene were prepared via phase inversion technique. The important parameters in manufacturing unfilled PVDF membranes including polymer concentration and content of additives were initially assessed. The effects of adding graphene to the PVDF membrane on its performance for desalination of a 3.5 wt% NaCl

A device approach to manage the emission color of the organic light-emitting diodes (OLEDs) which show two emission processes of thermally activated delayed fluorescence (TADF) and phosphorescence was developed by engineering the host of the emitter. The emitting material was phenyl(10-phenyl-10H-phenoselenazin-3-yl)methanone (PSeBz) which emitted at 496 nm by TADF process and at 559 nm by phosphorescence

In microfluidics, the emerging field of microphysiological systems (MPS) is overcoming the challenge of physiological irrelevancy by animal models for drug discovery and development. Liver function is critically influenced by drugs owing to its role in drug metabolism and detoxification. Human serum albumin (HSA) is one of the most important secreted biomarkers which indicate normal liver function

Toluene diisocyanate (TDI) is an important raw material to produce a flexible polyurethane foam, and the demand for TDI is growing as the polyurethane market is driven by high demand. The cold phosgenation reactor plays a vital role in the production of TDI, in that the overall reaction selectivity is determined and the most of by-product urea, which is critical to the entire downstream process, is

This study optimizes the extraction of phenolic and flavonoid compounds from Empetrum nigrum var. japonicum (crowberry) fruit using response surface methodology and evaluates the antioxidant activities of the extracts obtained. The optimized conditions predicted by Box-Behnken design were as followed: for total flavonoid content, extraction time is 43 min, extraction temperature is 52 °C, volume of

α,ω-Dicarboxylic acids (α,ω-DCAs) have numerous applications, as raw materials for producing various commodities and polymers in chemical industry. For example, dodecanedioic acid (DDDA), a monomer of nylon 612 polymer is used for numerous applications such as plasticizers and adhesive. In this study, firstly the enzymatic production of DDDA from corresponding ω-hydroxy fatty acid was optimized using
